IMO...on paper, the hp is meaningless, because there's always the ZL1 with more at 580...the hp junkies will gravitate towards that car.

The Z/28, on the other hand...isn't meant for high volume sales, and chances are only those who really understand it's purpose and value will buy it. These people care about lateral G's...brake equipment, and lap times...they know horsepower is just a part of the overall formula.

Chances are...imho...the addition of the CAI, and 3" exhaust all the way back will result in a 510-520 hp car...I think. But No. 3 could be completely right in saying it might not be recertified...
